SUPPORTING-FRAME FOR ELECTRIC-RAILWAY MOTORS.

SPECIFICATION forming part of Letters Patent No. 422,445, dated March 4, 1890.

Application filed January 24, 1889. Serial No. 297,373. (No model.)

. tion with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention relates to electromotors employed in the propulsion of cars or vehicles,

and has for its object to provide an efficient,

simple, and cheap support for the motor below the body of the said car or vehicle and independent thereof and of the truck-frame upon which the body is mounted, my improved support for the motor being capable of being readily applied to housings on the axles of a car or vehicle body of any usual design or form.

In accordance with my invention, the electromotor, which may be of any desired or usual type, is sustained or suspended below the car-body by a supporting-frame, preferably made of bars of rolled steel or iron of any desired shape, the said bars being bolted or otherwise secured together to form a strong frame, herein shown as substantially rectangular in shape. One end of the supportingframe will rest upon and be secured to suitable housings or boxes mounted 011 the axle of the truck, which may be of any usual or desired construction. One end of the supporting-frame, as represented in the embodiment of my invention hereincontained, is shown as sustained'by or through one or more auxiliary supports, preferably made as a bar or bars extended in the direction of the length of the car or vehicle, and preferably the end of the said supporting-frame will rest upon usual bufiers or springs or like yielding support, although the buffers or springs may be omitted. The armature-shaft of the motor is journaled in suitable boxes or bearings Figure 1 in side elevation shows two electromotors supported, in accordance with my invention, below the body of the car or vehicle, the bottom of which is represented by dotted lines; Fig. 2, a top or plan view to more clearly show the supporting-frame shown in Fig. 1, the body being omitted; Figs. 3 and 4, modified forms of auxiliary supportingframe; Fig. 5, a side elevation of a modified arrangement to be referred to; Fig. 6, a top or plan view to more clearly show the supporting-frame shown in Fig. 5; and Figs. 7 and 8, modifications to be referred to.

\ The car-body A, as well as the truck-frame upon which it is supported, are and may be ofany usual construction, the axles a a hav ing usual wheels A, (indicated by dotted lines in Fig. 1.) v

In accordance with my invention, one or both axles a a of the truck has mounted upon it between its wheels housings or boxes a". To the housings or boxes of one or both of these axles is secured, as by bolts a one end of a motor-supporting frame, consisting, as herein shown, of four bars, (marked a a a (0 the said bars being preferably of rolled steel or iron.

The end of the supporting-frame farthest from the axle is secured, as by bolts a to an auxiliary supporting-frame of suitable shape located above the motor-supporting frame and between it and the car-body A, the auxiliary supporting-frame being herein shown as composed of two bars b, extended in the direction of the length of the body, and having its opposite ends resting upon preferably yielding supports 1), which may be rubber buffers or springs, the said bars, as herein shown, being secured to the bars a a by bolts 11 The end of the motor-supporting frame which does not rest upon the housings or boxes 6& of the axle of the truck is herein shown as supported from the auxiliary supporting bars by a buffer 13*, on the bolt a The cross-bar 01. of the motor-supporting frame has secured to its under side, as by bolts b", a flange 19 of the field-cap or end piece I) of the motor, the said field-cap or end piece being shown as bolted to the fi.eld1nagnets 1). I

ICO

The armature c of the motor has its shaft 0 supported in hangers or boxes 0*, herein shown secured by bolts 0 to the under side of the bars a a of the motor-supporting frame, the said shaft being provided with the pinion c, in mesh with a gear 0 on a counter-shaft 0, having journals in hangers or boxes 0 represented as detachably secured to the side bars of the motor-supporting frame, the said eounter-shaft having a pinion e in mesh with the gear 0" on the axle a, by which gearing the rotation of the armature is transmitted to the axle of the truck.

One of the chief advantages of my invention is to enable the armature of the motor to be readily removed for purpose of repair-as, for instance, the field-cap b may be disconnected from the bar a and the hangers or boxes 0 unscrewed from the supportingframe, thus permitting the motor to be turned down on the counter-shaft c as a center, or nearly so, to prevent the wire on the field from coming in contact with the countershaft, a suitable joint or connection at the rear portion of the motor permitting the motor to be so turned.

To enable the motor to be turned, as described, t e rear end thereof is represented as supporter by the bars 11 b jointed togethelgas at b, the bar 11 being bolted or otherwise socured to the field-magnet b and the bar D socured, as by bolts Z), to the crossbar a of the motor-supporting frame; but I do not desire to limit my invention to the exact form of connection shown. A

If desired, the motor may be readily removed without disturbing the supportingframe by disconnecting the arm 11 from the fieldqnagnets at its rear end and the fieldcap or end piece I) at the front end of the motor and removing the hangers c 0 the motor being then. free to be dropped below its frame.

It will be noticed that the car-axles are not rigidly connected together, but that they have substantially the same freedom of motionfas they would llElNO with the motor and supporting-frames omitted.

By making the niotor-supp0rting frame of rolled steel or iron lightness coupledwith great strength is obtained, while the elasticity of the metal largely prevents sudden shocks and jarring of the motor.

If desired, the motor and its supportingframe and auxiliary frame may be protected by a covering.

The supporting-frames are entirely independent of the car-body, so that movement .of the same does not affect the motor. The motor may be located at either side of the axle.

Fig. 5 showsthe motor-supporting frame as located outside the axles rather than between them, as in Fig. 1.

I may use one or two motors, and, if desired, one motor may be supported between the axles and the other beyond one axle below the end or what may be the platform of the ear; or four motors may be used-as, for instance, by combining the arrangements shown in Figs. 1 and 5-50 that two motors are located between the axles and one at each end outside of the said axle.

I do not desire to limit myself to the partieular form of auxiliary supporting-frame shown in Figs. 1 and 2, as other forms maybe used, sueh, for instance, as shown in Fig. 3, where two bars I) are united by cross-bars (Z, substantially in line with the axles of the car-truck; or a single bar I), as shown in Fig. 4, maybe employed, it being supported at its ends by buffers b and secured to the sup porting-frames.

In Fig. 1 I have shown the ends of the auxiliary frame resting upon buffers supported above the axles, but it is evident that they may be supported by the side bars of the motor'supporting frame,

Referring to Fig. 1, a buffer 12 or other yielding cushion is placed upon the belt a, between the motor-supportin g frame and the auxiliary supporting-frame, so that on the reversal of the motor the upward thrust, caused by the tendency of the motor-supporting frame to turn about the car-axle as a center, is checked or taken up by the said buffer,

' thus relieving the motor from jar.

When a single bar I), as shown in Figs. 4 and 8, is employed as the auxiliary supporting-frame, it will preferably extend over the motors from about the center of the axle, it resting upon suitable buifers I).

hen the auxiliary supportingframe shown in Figs. 3 and 7 is used, the buffer b b on the bolt a will preferably be located in the longitudinal center of the bar (Z.

I have herein described the motor-supporting frame which surrounds the motor as com posed of bars bolted together, but .it is evident that the said frame may becast in one piece.

The bolts securing the motor-supporting frame to the auxiliary supporting-trame are permitted to have a'freedom of motion, as herein shown, by enlarging the holes through which they are extended.
